My present invention has to do with the protection of gasoline lamps, particularly the mantle thereof from insects, and has for its object to provide an efficient screen for the purpose indicatechand one adaptedto be applied without disconnecting the lamp,

lighted and controlled withoutdiminishing in any degree the efficiency of the screen in barring insects from the mantles;

'Other objects and practical advantages of the invention will be fully understood from the following description and claims when the same are read, in connection with the drawings, accompanying and forming part of this specification in which Figure 1 is a view partly in elevation and partly in section the preferred embodiment of my invention as the same appears when properly applied to a gasoline lamp, I Figure 2 is a plan view of the top member of my improvement.

Figure 3 is a horizontal section taken:

through the screen or wire mesh cylinder of my improvement looking downwardly' Figure 4 is a fragmentary vertical section illustrating the manner in which the bottom of the screen is connected with the 'annulus at the lower end of the cylinder ofreticulated material. Figure 5 is a fragmentary vertical sec tion illustrative of the manner in which the door at the bottom of the screen isremov ably secured in working position. i h 3 Figure 6 is a detail longitudinal vertical section of the said door.

Similar numerals of reference designate corresponding parts in all of the views of the drawings. 7 p y I show in Figure 1 a conventional or well known type of gasoline lamp having a stem 1, mantles 2. ahead portion 3 and springs 4 adjacent to the said head portion 3. the said springs 4 being designated to support a globe, not shown. v

The said lamp is not of my invention, but is merely shown to facilitate an understanding of the application. of my improved in illustrating the screen.

portion 14 and My novel screen is applied at the top.

of the lamp and is moved downwardly to proper working position relative to the lamp."

Among other elements my improvementincludes a top member 5 made up of a central apertured portion 6, an annulus 7' and a portion 8 of wire screen or reticulated'material interposed between the central portion 6 and the annulus 7 Thesaid member 5 is designed to fit'in the top portion of the lamp with a view to preventing insects from gaining access to the'lamp at the top.

My improvement also comprises a cylinder 9 of 'wire screen or reticulated material permanently connected at its upper j end to a dome portion 10, preferably of sheet metal and preferably'shaped as shown. In this'connection it'will be understoodthat the dome portion 10 shaped as illustrated is calculated to, fit snugly on the springs 4;

At its lower. end the cylindrical screen or body 9 is provided with a -metallic annulus 11, Figures 1 and 3, the said a'nnulusll being permanently connected to the lower end of the wire screen cylinder by any approved means 'andbeingcprovided with in;

wardly extending spaced lugs 12 Figures 3 and 4. r v

The bottom member "ofmy 'novel'screen' is made up of a also having an opening '15 the side walls of whichllatter are designed to rest at opposite sides of the stem 1 of the lamp. Struck up from the annular p0rtion" 14 of the frame 13. are resilient tongues .16 which are adapted when slightly deflected from the plane of thelannular portion '14 to be'moved' into engagement with the lugs 12; as shown in Figures 3 and '4; inorder to rest above and in frictional contact with the said lugs 12 so thatwhilethere'is no liability of thefbottom member being casually displaced, yet it may be expeditiously and easily removedfromthecylindrical body 9 when desired. It will also be understood framef 13- having annular that the bottom member being'detachablysecured through the medium ofthe tongues 16 in'engagement with the annulus 11; the bottom member may be quickly'iand easily,

and at the same time strongly connected to the cylindrical body 9. i

The frame of the bottom member 13 is also provided with flanges 17 at opposite sides of the before mentioned opening 15, and slidably engaged with the said flanges 17 and supported thereon. a doorlfi which serves after which the bottom member is disasso-' when closed to bar insects at the lower end of the protective screen and also serves when opened to permit the ready ignition of the lamp. 1

Incident to the removal of the protective screen, the sliding door 18 is removed first,

ciated from the wire screen body 9 and is removed edgcwise, after which the body 9 may bemoved upwardly from and out of engagement with the lamp. In the placing of my improvement the operation described is reversed.

It will be appreciated from the foregoing that my improved screen is susceptible of ready application and removal, is not calculated to interfere in any measure with the proper operation of a gasoline lamp, and is well adapted to exclude insects from the lamp with the result that liability of injury by insects to the mantles or other parts of the lamp is reduced to a minimum. I

It will also be appreciated that generally considered, my novel screen is simple and inexpensive in construction, and that as a whole the screen is well adapted to withstand the usage to which gasoline lamp appurtenances are ordinarily subjected.

I have entered into a detailed description of the construction and relative arrange ment of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear and exact understanding of said preferred embodiment. I do not desire, however, to be understood as limiting myself to the precise construction disclosed, my invention beingdefined by my appended claims, within the scope of which modifications or changes in structure may be made WitlIOUtdGPELTtUIC from my invention.

Having thus described the invention, what I claim as new and desire to secure by Let ters Patent is 1. In an insect proof screen for gasoline lamps, and in combination, a cylindrical bodyofreticulated material adapted to be supported in position. about a gasoline lamp and havingan annular portion at its lower end, a bottom member made up of a frame and wire screen or reticulated material carried' by. said frame, said, frame having a radial opening to receive the stem of a lamp and also having tonguesto engage portions of thesa-id annulus at the lower end of the body and further having means for engaging and supporting a radially movable slid- I 7 able door, and a door engaged with and supported by the bottom member and removable radially to expose the said opening of of said annulus at the lower end of the body and further having means for engaging and supporting a radially movable slidable door, a door engaged with and supported by the bottom member and removable radially to expose the said opening of the body member; 1

the said tongues of the frame in the bottom member being struck up from said frame and being possessed of resiliency, and the said annulus at the lower end of the wire screen body being provided with inwardly directed spacedlugs for the engagement of the said tongues.

3. An insect proof screen for gasoline lamps, comprising a cylindrical body of reticulated material, a dome portion connected to said body and adapted to be supported on the spring of a lamp, a central top member having a central apertured portion, an annulus, and Wire screen interposed. between and connected to the central portion and the annulus, and means for closing the lower end of the'cylindricalbody, said means detachably connected with the body and having a wire screen portion and an opening to receivethe stem of a lamp, and also having a removable door adapted when closed to bar insects, and when open to permit of ready ignition of a lamp.

4.. In an insect proof screen for gasoline lamps, in combination, a body of reticulated material adapted to be maintained about the mantle portion of agasoline lamp, a bottom member detachably connected with said body and having ,a radial opening whereby it may be made to straddle the stem of a gasoline. lamp, and a removable door associated with said opening for the barring of insects when the door is closed and for permitting of ready ignition of the lamp when the door is opened.

In testimony whereof Iaflix my signature.
